Tese (Doutorado) — Universidade de Brasília, Faculdade de Ciências da Saúde, 2018.; A epilepsia é uma das doenças neurológicas mais comuns em todo o mundo. O objetivo dessa pesquisa foi buscar por moléculas úteis à farmacoterapia de crises epilépticas, a partir da peçonha de vespas sociais. Inicialmente, foi feita a coleta e extração de peçonha das vespas Chartergellus communis. Após obtenção desta, foi feito o...
In last years, considerable efforts have been made to identify neuroactive and neuroprotective peptides derived from the venom of different natural species. In this work, were studied the activity of Dinoponera quadriceps native (DqV) and denatured (DqDV) venom on chemically induced seizures models in vivo and on in vitro cortical astrocytes viability. Male Swiss mice (28- 33g) were pretreated with DqV (0.1 or ...
Arthropod venoms are potential sources of neuroactive substances, providing new tools for the design of drugs. The aim of this study was to evaluate the effects of Dinoponera quadriceps venom (DqV) on seizure models in mice induced by pentylenetetrazole (PTZ), pilocarpine, and strychnine. In the PTZ model, intraperitoneal treatment with DqV (0.5 mg/kg) increased the time until the first seizure and the percenta...
